So my daughter is 3 months old & she has always been exclusively breastfed but I'm going back to work two nights a week…

Have somebody else offer the bottle when you aren't around. Sometimes you will find its not the bottle. It's like...if your favorite cup is clean why would you get one from the sink and wash it to use?

Babies often won't take a bottle from the mother because....well, the boobies are right there and those are better lol. Walk out of the room and have someone else offer the bottle.

im kinda in the same sistuation. u have to kinda teach them how to suck from bottles, their not used to it try buying one bottle of different brands. Brestfeed her then when shes not hungry (but not full) try to introduce her to the bottle. Find the nipple she likes most, she wont start sucking right away but it gets her familiar with bottles. Also have your SO try feeding her. Im starting to do this twice a day because i have to return to work in a couple of months.

Keep trying bottles. I know it's a lot of money but I had to go through so many before my son took one which is avent. The only one he'll take
